Help customers calculate
before they contact you.
Give visitors a useful estimate, comparison, or planning result with formulas and assumptions you control. Use calculators to clarify a decision—not to disguise a sales pitch as precision.
How to choose
Start with the customer decision—not the widget.
- 01
Choose the result the customer genuinely needs: cost, savings, ROI, quantity, area, payment, or margin.
- 02
Show assumptions and label estimates clearly so the result is not mistaken for a binding quote.
- 03
Ask for contact information only when follow-up adds value; do not hold a basic result hostage.
- 04
Test realistic minimums, maximums, zero values, mobile input, and rounding before publishing.

Questions before choosing
Platform, privacy, and fit.
Can I customize the calculator formula?
Yes. Calculator products include visual setup for supported inputs and formulas. Check the individual tool for its calculation engine and configuration limits.
Is a calculator result a quote?
Not unless your business explicitly makes it one. Most implementations should identify results as estimates and explain exclusions, assumptions, taxes, or site-specific variables.
Do calculators capture leads?
Some configurations can pair a result with a next step. Collect only what you need and explain how submitted information will be used.
Which platforms are supported?
The collection supports common embed approaches across modern website platforms. Review each product’s platform and installation notes before purchase.
Own the tool. Keep the flexibility.
Customize visually, export the files, and host core operation on infrastructure you control.
